Massachusetts prosecutors filed paperwork on Thursday alleging that former New England Patriots tight end Aaron Hernandez openly discussed the slaying of Odin Lloyd in recorded phone calls he made while in prison.

The Bristol County district attorney's office requested copies of the recordings of Hernandez's phone calls in addition to a copy of his visitors log since his arrest.

The affidavit, written by Bristol Assistant District Attorney Roger L Michel Jr., details what the prosecution believes Hernandez has been discussing in code:

"During those conversations, the defendant has discussed the following matters directly relevant to the circumstances surrounding the murder of Odin Lloyd; viz: the defendant's subjective belief about his criminal liability; his use of coded messages to communicate with persons outside of jail; related prior offenses; inculpatory denials of ownership of a vehicle connected with the investigation; the extent of his control over persons charged as accessories; other matters relating to his codefendants, including their whereabouts and likely criminal liability.''
